Census data and the Fragile Families survey show that marriage can be extremely effective in reducing child poverty. But the positive effects of married fathers are not limited to income alone. Children raised by married parents have substantially better life outcomes compared to similar children raised in single-parent homes.

When compared to children in intact married homes, children raised by single parents are more likely to have emotional and behavioral problems; be physically abused; smoke, drink, and use drugs; be aggressive; engage in violent, delinquent, and criminal behavior; have poor school performance; be expelled from school; and drop out of high school.[19] Many of these negative outcomes are associated with the higher poverty rates of single mothers. In many cases, however, the improvements in child well-being that are associated with marriage persist even after adjusting for differences in family income. This indicates that the father brings more to his home than just a paycheck.

The effect of married fathers on child outcomes can be quite pronounced. For example, examination of families with the same race and same parental education shows that, when compared to intact married families, children from single-parent homes are:

More than twice as likely to be arrested for a juvenile crime;[20]

Twice as likely to be treated for emotional and behavioral problems;[21]

Roughly twice as likely to be suspended or expelled from school;[22] and

A third more likely to drop out before completing high school.[23]

The effects of being raised in a single-parent home continue into adulthood. Comparing families of the same race and similar incomes, children from broken and single-parent homes are three times more likely to end up in jail by the time they reach age 30 than are children raised in intact married families. [24] Compared to girls raised in similar married families, girls from single-parent homes are more than twice as likely to have a child without being married, thereby repeating the negative cycle for another generation.[25]

Finally, the decline of marriage generates poverty in future generations. Children living in single-parent homes are 50 percent more likely to experience poverty as adults when compared to children from intact married homes. This intergenerational poverty effect persists even after adjusting for the original differences in family income and poverty during childhood.[26]

People on the left claim that poverty causes crime, but they don’t look for the root cause of poverty. The root cause of poverty is the decline of marriage. But people on the left favor that, so they can’t admit the truth.

Dr. Michael Tanner of the libertarian Cato Institute explains one of the causes of fatherlessness in his testimony to Congress:

Welfare contributes to crime in several ways. First, children from single-parent families are more likely to become involved in criminal activity. According to one study, children raised in single-parent families are one-third more likely to exhibit anti-social behavior.(3) Moreover, O’Neill found that, holding other variables constant, black children from single- parent households are twice as likely to commit crimes as black children from a family where the father is present. Nearly 70 percent of juveniles in state reform institutions come from fatherless homes, as do 43 percent of prison inmates.(4) Research indicates a direct correlation between crime rates and the number of single-parent families in a neighborhood.(5)

As Barbara Dafoe Whitehead noted in her seminal article for The Atlantic Monthly:

The relationship [between single-parent families and crime] is so strong that controlling for family configuration erases the relationship between race and crime and between low income and crime. This conclusion shows up time and again in the literature. The nation’s mayors, as well as police officers, social workers, probation officers, and court officials, consistently point to family break up as the most important source of rising rates of crime.(6)

At the same time, the evidence of a link between the availability of welfare and out-of-wedlock births is overwhelming. There have been 13 major studies of the relationship between the availability of welfare benefits and out-of-wedlock birth. Of these, 11 found a statistically significant correlation. Among the best of these studies is the work done by June O’Neill for the U.S. Department of Health and Human Services. Holding constant a wide range of variables, including income, education, and urban vs. suburban setting, the study found that a 50 percent increase in the value of AFDC and foodstamp payments led to a 43 percent increase in the number of out-of-wedlock births.(7) Likewise, research by Shelley Lundberg and Robert Plotnick of the University of Washington showed that an increase in welfare benefits of $200 per month per family increased the rate of out-of-wedlock births among teenagers by 150 percent.(8)

The same results can be seen from welfare systems in other countries. For example, a recent study of the impact of Canada’s social-welfare system on family structure concluded that “providing additional benefits to single parents encourages births of children to unwed women.”(9)

The poverty that everyone complains about is not the root cause of crime. The poverty is caused by fatherlessness. The fatherlessness is caused by welfare. Fatherlessness is also caused by laws and policies that make it easier for people to divorce, e.g. – no-fault divorce laws. Again, it’s people on the left who push for no-fault divorce laws. So the left is pushing two policies, welfare and no-fault divorce, which cause crime.

How do we stop this? We go after the laws and policies that promote fatherlessness. No-fault divorce laws make it easy to get out of a marriage, which means that people rely on “chemistry” and peer-approval to decide who to marry instead of choosing the right person for the actual duties of the job. The divorce court system rewards the person who files for divorce first, which is the women in about 70% of the cases. The incentives all favor fatherlessness.

If we were serious about fixing fatherlessness, we should reform divorce laws to make people take marriage more seriously. Instead of giving alternatives to marriage the same benefits as marriage, we should give benefits to people who are able to get married, stay married and produce productive, law-abiding children.
